IRCTC Chart Preparation Time Indian Railways-When and How many hours before the chart is prepared and when the chart is prepared for morning trains.May people are very confused about when the reservation chart is prepared for departing trains.Here is a simple logic behind the final chart preparation timings of Indian railways.

For the trains starting between 12 pm(After Noon) to 12 am(Mid Night),chart preparation is done 4 to 6 hours before departure of train. 

For the trains starting between 12 am(Mid-Night) to 12 pm(After Noon),charts are prepared on the previous night around 8 to 9 pm.

Suppose you have a train at 1 pm on 1st Jan then the chart will be prepared around 8-9 am (same day).
For the train starting at 6 pm the chart will be prepared at around 2-3 pm(same day).

For the train starting at 10 pm the chart preparation is done at around 6-7pm.
And if you have a train between 12 am(2 Jan)  to 12 pm(2 Jan) ,then the chart preparation is done at around 8 pm(1 Jan).
